Help please

[Guest pks1414]

I have put together a small airfield complete with AFCAD and AI. I have put parking spots and a taxiway with some hold shorts. For some reason and I just cannot figure it out, if 2 planes come out at the same time, in this case a cherokee and a cub, they crash into each other or get mighty close. In addition, although I have a hold short node, the cub inevitably goes into the cherokee. I noticed as well that a plane crossed the stripeven though another was cleared for take off.What am I doing wrong here,any help would be really appreciatedThanksPaul

I see "getting close" all the time with GA. I wouldn't consider that a problem. Collisions *might* be avoided if you make the node that enters the RW closest the parking area, a HS node, or simply join it to the adjacent taxiway. I say *might* because nothing in AFCAD seems to be written in stone. I'm working on one in CA right now, that when set up "by the book" it doesn't work properly. When AI collide, I seperate the A/D times a little more.Hope this helps,Mikewww.aimadeeasy.comwww.flightontario.comI'm confused. Wait...maybe I'm not!
